IMPROVEMENT IN BEER-FAUCETS.

Specification forming part of Letters Patent No. 160,242, dated February23, 1875 application filed March 1'7, 1874.

To all whom it may concern:

Beit known that I, MICHAEL J AMES SUL- LIVAN, of the city, county, andState of New York, have invented an Improved Beer- Faucet, of which thefollowing is a specification:

This invention relates to a metallic faucet of superior simplicity,provided with air-inlets for venting the barrel or keg, and a pump orejecter for foaming the beer in the glass, and operated by a singlehandle, as hereinafter set forth, theimproved faucet being opened orclosed by a quarter-turn of the valve or plug in either direction.

Figure l is a vertical longitudinal section of this improved faucet.Fig. 2 is a horizontal section of the same. Fig. 3 is a transversesection, with the valve or plug in elevation. Figs. 4 and 5 arehorizontal transverse sections of the plug in diii'erent planes. Fig. 6is an eleva-tion of the lower end of the combined handle-stem andplunger.

-The planes of the several sections are indicated by linescorrespondingly numbered.

This faucet is composed of two principal members, A B, of which thesocket-member or stock A has the customary hollow conical shank z, toenter the tap of a barrel or keg, and a head, y, by which to drive it.The extremity of the shank is closed, and its sides are perforated toform a strainer for the admission of the beer into the cavity x of theshank, which opens into the lower part of the socket. An air-tube, w,extends longitudinally through the shank from the upper part of thesocket to the center of the eirtremity of the shank. The valve or plug Bsits vertically in the socket of the stock A, fitting the same tightlyso as not to leak, and turning therein. The plug is held in position,and tightened as required,by a nut,v,on a threaded portion of its lowerend, beneath a springwasher, u, and is operated by a handle, t, appliedto a central rod or stem, s, at the upper end of the plug. From thebeer-port in the socket downward a certain distance the plug isconstructed with two concentric chambers, 1' q, of which the innerchamber q receives a plunger-extension, p, of the handle stem s toconstitute a pump 5 and the annular chamber r continues unobstructed tothe nozzle-opening n. Ports o o2 give the beer access to these chambersrespectively in each of two open positions ofthe plug, but only to theinner chamber qwhen the plunger p is elevated, as in the illustration.Beer thus admitted to the pump-chamberqfills the same, and is forciblyejected into the glass through a very minute f orifice in asupplementalnozzle, n2, by depressing the handle and plunger. A suitable packing isapplied to the lower end of the pumpplun ger p, as illustrated in Fi g.6. Theupper end of the plug has a central square recess, m, whichreceives a squared enlargement, Z, on the combined handle-,stem andplunger, to adapt the latter to turn the plug, and to be reciprocatedlongitudinally independently of the same. An annular screw-cap, 7c,applied to the upper end of the plug, closes the same and connues theplunger.

The plug is provided within the socket, above its beer-ports, withhorizontal segmental grooves j, arranged to operate simultaneously withsaid ports. These grooves form a chaunel leading to the air-tube w froman airpassage, c', in the side of the stock. This passage does not openoutward directly, but is extended downward, in a vertical direction, toa point at or near the bottom of the socket, as shown in Fig. 3.

In Figs. l, 2, and 3 this faucet is represented as fully opened, so asto admit air, and to discharge the beer into the glass, and also intothe pump-chamber q. When the glass has been lled the ow may be stoppedby turning the plug, and then, or previously, the contents of the pumpmay be ejected to foam the beer by depressing the handle and plunger.

The faucet is opened or closed, as the case may be, by a quarter-turn ofthe plug in either direction. This is a feature of considerablepractical value, owing to the loss of time and wastage which itobviates.

The construction of the pump permits the employment of a minutedischarge-aperture, and obviates dipping the nozzle in the glass. Thecombined handle-stem and plunger with square enlargement possessessimplicity and strength in a superior degree, while the single handleprovides for completing the operation without removing the hand. Thevertical airpassage possesses a decided advantage over duplicatedhorizontal air-grooves j in the periphery above the said. ports, and asquare socket, m, in the upperend of theplug, as herein shoWnAanddescribed, for the purposes set forth.
